I believe so. You can control the hydration with soap. With a can, you get what you are given.Is there any advantage to soap you lather up with a brush in a cup over aerosol shaving cream when using a straight razor or is it strictly about the traditional experience?
Not a time issue just curious if there's really a functional difference - the consensus seems to be that there is. If for some reason I were in a huge hurry I'd use the electric.
